To many people, the Marx Brothers always seemed cartoonish. Small wonder that film animators plucked their personas from their first appearances in The Cocoanuts (1929) and Animal Crackers (1930) and caricatured them in countless animated appearances in theatrical cartoons. Their animated likenesses have since been wisecracking in television cartoons, direct-to-video movies, fan films, commercials, flip books, avatars, emoji, a slot machine, and two TV pilots so rare they were once thought not to exist.

This book traces the diffusion trajectory of the second and third generation of British steam engines, the Watt and high-pressure models, covering the period 1774 to 1870. It begins by subjecting to econometric analysis the latest version of Dr. Kanefsky's database on 18th century steam engines coming up with an upward revision of the total amount of horsepower installed by 1800. Subsequent chapters delve into the determinants of the diffusion process through the third quarter of the 19th century relating to engines used both in mining and industry as well as transportation (railways, steam cars).
